Larchmere makes plain spreadsheet templates. You buy the file once and it is yours to use, with no subscription, no macros and no add-ons.
First on the shelf is a budget workbook you fill by pasting your bank's transactions instead of typing them. You write the rules, it does the adding up, and its check lines show whether the totals tie back to your rows. Arithmetic only: nothing here is a recommendation.
It was made with the help of AI tools and checked by hand in Google Sheets and Excel for the web.
